Liblouis is an open-source braille translator and back-translator named in
honor of Louis Braille. It features support for computer and literary braille,
supports contracted and uncontracted translation for many languages and has
support for hyphenation. New languages can easily be added through tables that
support a rule- or dictionary based approach. Liblouis also supports math
braille (Nemeth and Marburg).
Liblouis has features to support screen-reading programs. This has led to its
use in two open-source screen readers, NVDA and Orca. It is also used in some
commercial assistive technology applications for example by ViewPlus.
Liblouis is based on the translation routines in the BRLTTY screen reader for
Linux. It has, however, gone far beyond these routines.
